Automobile Safety

Secure the pet in the car. An unrestrained pet can interfere with driving and become a hazardous projectile in the event of an accident or sudden stop.
Crates or sturdy pet carriers are an ideal way to restrain pets in cars. Stressed pets need a nice quiet place to rest and be alone at times. Secure the crate so it does not fly forward or flip in case of a sudden stop or accident.
If your car does not allow room to set up a crate, obtain a dog seat belt, which doubles as a harness.
Another reason to keep pets in the back seat or in a crate is that airbags can pose hazards to smaller people and pets. Air bags can launch out of the dashboard at a great enough force to severely injure a pet.
Install a pet barrier to keep dogs in the back seat.
Secure pets so that they cannot hit buttons for electric windows, adjustable mirrors, etc. Pets have gotten their heads stuck in electric windows after activating them.

Be sure to keep the dog's leash firmly in hand when loading and unloading the dog from the car. Always keep a current i.d. tag on the pet in case the pet manages to escape. Make sure the collar cannot slip off.

Pets are at risk in convertibles with the tops down and in the open bed of a pick-up truck.
Avoid letting dogs stick their heads out the car window, which can lead to eye, ear and other injuries.
If your pet gets motion sickness, there are different types of pharmaceuticals that may help. Speak to your veterinarian about which mediation would be right for your pet.
